The mission objective for Blok Copy is simple; the playfield contains seven distinct designs of tile arranged into columns of five and, at the start of each level, those tiles are shuffled around; the operator must then reorganise those tiles to resemble their starting order to unlock the stage and progress to the next until all ten levels have been re-synchronised. The joystick directions move the four cursors placed at the edges of the play area and holding the fire button down and moving simultaneously will shuffle the highlighted row or column.

Based on source code from the Commodore PET version released in 2008, Blok Copy is the first release for Cosine on the C64DTV. In order to run it, you'll need a modified C64DTV with 8 bits per pixel graphics (version 2 or 3) or the C64DTV emulation now included with VICE

Trivia: The original Blok Copy (the still unreleased Atari 2600 version) took a mere 4K of ROM, the PET code was squished into a mere 8K and yes, we're aware of the irony since the C64DTV2 uses 32K just for the graphics!
